Any time two different genes contribute to a single phenotype and their effects are not merely additive, those genes are said to be epistatic.

In classical genetics, if genes A and B are mutated, and each mutation by itself produces a unique phenotype but the two mutations together show the same phenotype as the gene A mutation, then gene A is epistatic and gene B is hypostatic.
